Here is a dump of the version 4.00 dev_flash.
I dump my earlier leaked firmware 3.73 (Available for download in the “Download“), but my site was still under construction and I lost a lot of time to update due to the time I devote to my studies (Terminal LAC) and I did not have much time was devoted to the scene. During the holidays I am responsible, but I will try to give as much information as possible waiting for a response from Kakaroto.
I shared these dumps for the attention of developers to program an emulator we dev_flash. For those who want to test dumps on 3.41JB with “FIRM JaiCrab Load” because you can try on my side, I used “CFWLoad 1.0″ in 3.41JB (PL3).
Emulation looked heavy, I do could not leave the program because after a few seconds the console would have been totally blocked. I thought at first the problem was my jailbreak. However, this was not the case, because after I tried with a 3.41 dump (edit) and loading it well. I finally concluded that the emulator should help the dev_flash home to work, for this reason that when you make a NAND emulated with SHIFT it resets everything to ultimately make a regular MAJ that will change the real dev_flash your console. Attention, the emulator does not emulate completely dev_flash stored in your USB drive. (Internal HDD etc …).
If developers are interested in these dumps, I hope they will do something. I for my part I work on the Factory / Service Mode firmware higher than 3.56 and the Nintendo 3DS.
